SILO-DOOR.

Specicaton of Letters Patent.

Patented July 22, 1913.

To all whom t may concern:

Be it known that I, MERLE W. DoU'rHETT, a citizen of the United States,residing at Superior, in the-county of Nuckolls and State of Nebraska,have invented a new and useful Silo-Door, of which the following is aspecification.

`This invention relates to silos, and more particularly to the doormountings thereof.

The present invention contemplates the provision of a novel and improvedmeans for mounting the doors to the door-frame of the silo, seat againstthe inner side' of the door frame and toswing inwardly within the silo1n or der to open the silo.

This invention also aims to provide a device of this character whichwill enable the doors to swing inwardly within a small compass and in aconvenient manner.

This invention among its other objects, aims to provide a noveldoor-frame or jambs for the door opening; to provide a door mountingadjustable vertically upon one of the door jambs; to provide means forlimiting the swinging movement of the improve devices of this characterso as to provide a simple, substantial and inexpensive structure, whichwill be convenient and efficient in use.

With the foregoing and other objects in view,which will be apparent asthe invention is better understood, this invention re sides in the novelconstruction and combi-- nation of parts hereinafter set forth andparticularly pointed out in the appended claims, it being understoodthat this device is susceptible of alterations or deviations of itsdetails within the scope of the appended claims without departing fromthe spirit of the invention.

The invention is illustratedin its preferred embodiment in theaccompanying drawings, wherein similar reference characters have beenIemployed to denote corresponding parts, and whereinz--f Figure 1 is afront view of a fragmental portion of a silo embodying the present inlvention. Figs. 2 and 3 are sectional views taken on the lines 2-2 and3-3 of Fig. 1, respectively. Fig. 4 is a View similar yto Fig. 3` withthe door swungopen, Fig. 5 is a perspective view of certain detailsemployed in carrying out the present invention,

in order to permit the doors to' the several parts being separated. Fig.6 is a perspective view of a detail employed in carrying out theinvent-ion.

Referring specifically to the drawings, the sllo has been designated bythe numeral 7, which has a lon tudinal or vertical door opening 9extending throughout the length thereof, as usual. The silo structuremay be of any suitable type, preferablyof staves.

In carrying out the present invention, the jambs 10 are secured alongthe edges of the door-opening, the said jambs being constructed ofT-iron with the webs and one of the flanges secured to the edges of thestaves along the door-opening. The flanges of the `Tiron are disposedoutwardly, one flange of leach jamb being secured over the outer orexterior side of the staves adjoining the door-opening and the other[lange projecting inwardly relative to the door opening. These jambs 10may run throughout the length of the door-opening or doorway 9 andprovide a suitable door frame, as well as protecting the sta-ves alongthe edges of the door-opening. It will therefore follow that the said'ambs prevent injuries to the staves along the edges of the door framefro-m the removal of the ensilage from the silo, or from other causes.Cross-bars 1l are secured over the doorway 9 at intervals along itslength, the said bars dividing the door-opening or doorway into aplurality of .sections` and the said cross-bars may well be portions ofthe straps encircling the silo to retain the staves in position,although the latter need not be the case and is of no moment.

The doors for the various sections of the door-opening are designated bythe numeral 8 and are seatable against the inner sides of thedoor-frame` the said doors havingl the vertical bars 23 secured theretoalong their edges. which are designed to tit between the door jambs whenthe doors are seated against the door jambs. These doors may be of anypreferred construction, and are preferably superposed one above theotherl along the length of the doorway. The improved means for mountingeach ofthese doors 8 embodies two pairs of U-shaped clips straddling theinner or free -flange of one of the door jambs between the cross bars11, each of the clips having an ear 13 bent outwardly from one edge ofits outer arm` and forming a bearing for bolts or rods 15 which passthrough the said ears 13. Set-screws 14 are also carried by the outerarms of the clips 12 andareadapted to bind the clips to thecorresponding flange of the door j amb, and it will appear that byloosen ing or unscrewing the set-screws 14,` the clips 12 may beadjusted vertically along the corresponding jambs as desirable ornecessary. The clips 12 in being thus engaged to the flange 'of the doorjamb may be attached to the flange at any suitable point along itslength withoutdrilling holes in the flange or otherwise marring orinjuring same. l

A pair of hanger arms 16 are pivoted to the respective rods 15 betweenthe corresponding ears or bearings 13 of the clips,

each of the said arms being bowed outwardly or being L-shaped and havingits extremities bent in to the eyes 17 and 18, the eyes 17 of the 'armsengaging or encompassing the rods 15.

A pair of bearings 22 are secured to the exterior or outer side of eachdoor 8, the said bearings being preferably in the form of straps securedat their ends to the door and looped intermediate their ends to :formthe bearing, and an upright rod 19 passes through the saidfbearings andis 'bent angularly outside of the bearings to form hanger arms 2O withthe `free ends bent angularly or toward each otherto form pintles 21,the pintles 21 being received by the eyes 18 at the free ends of thehanger arms 16 so as t0 pivot the'free ends of the two pairs of hangerarms together. Nuts 24 may be engaged on the ends'of the pintles 21 inorder to'retain the respective hangerl arms in engagement with eachother. The bearings 22 are provided with stops 25 co-acting with thehanger arms 20 in order to limit the swinging movement of the door 8, sothat the edge of the door adjacent the hanger arms 16 may not be swungexcessively toward the said arms. In this manner, the door may bereadily opened by an inward pressure at any point thereon, and the doormay be swung inwardly without binding or without the edgeadjoining thearms 16 swinging toward the said arms, vwhich,

would tend to impair the opening of the door. With the door mountingthus provided,it will beseen that the door may be readily andconveniently swung inwardly within the silo away from the door-openingand within a small compass. The doors when swung outward so as to seatagainstv the inner side of the door frame will ef.-A

fectually close the doorway, and may be locked or clainped in closedposition in any suitable manner, which it is not necessary to illustrateor describe in detail. It will also be noted that the doors 8 may beadjusted vertically as desired or necessary, and the hanger arms 20 willpermit the doors to .the inner sides of the jambs,

shift laterally so as to properly seat against the door frame, the saidhangerl arms also serving to permitthe doorto open within a smallercompass than ordinarily. The arms 16 may 'also be adjusted verticallyupon the rods 15 so as to permit the doors to shift vertically due tothe expansion or contraction of the silo or doors therefor..

Door jambs of the particular form provided, not only forma substantialand suitable ydoor framefor the attachment of the door mountings, butalso preventinjuries tothe staves adjoining'theydoonopening when theensilage is removed, or due to other causes. The present door mountingis silage undergoing the curing or cooking process.

The various hanger arms 16 throughout the doorway will also bepositioned on the exterior. of. the 'silo when the doors are closed, sothat the various hanger arms form rungs which will serve as a ladder soas to enable a workman or attendant to ascend the silo. Y Havingthusdescribed the invention, what is claimed as new is y 1. Thecombination with a silo having a. doorway, of jambs secured to the edgesof the silo along the doorway land including flanges projecting inwardlyrelative to the doorway, clips attached to one of said flanges, a doorseatable against the inner sides of the jambs, and hanger arms pivotedto the exterior side of the door and pivoted to the said clips. j

2. The combination with a silo having a door opening, of jambs securedto the silo along the edges of the opening, and including flanges, clipsadjustable upon one of the flanges and inclu-ding bearings, means forclamping thel Vclips to the flange, a door seatable against the innerside of the jambs, and hanger arms pivoted to the bearings and to theexterior side of the door.

8. The combination with a silo having 'a doorway, ofejambs secured tothe edges of the-silo along lthe doorway` and including flangesprojecting inwardly relative to the doorway, U-shaped clips straddlingone of the flanges and having bearings projecting from their outer arms,a set-screw carried by one arm of each of the clips for binding same tothe flange, a door seatable against 'and hanger arms pivoted to thebearingsfand to the exterior side of the door. f

4. The combination witha silo having a doorway, of jambs secured to thesilo along the edges of the doorway, and including flanges, two pairs ofbearings adjustable upon one of the flanges, a rod passing through eachpair of said bearings, a door seatable against the inner sides of thejambs,

and hanger arms pivotally connected to said rods and connected to theexterior side of the door.

5. The combination with 'a ysilo having a doorway, of T-iron jambehaving their webs and one of their flanges secured ltothe edges of thesilo along the doorway, bearings connected to one of the free flanges, adoor seatable against the inner side of the jambs, and
